"The Uffenbach brothers are visiting Cornelis van Arckel in Rotterdam, and are looking at his collections. They enter his library, consisting of 2000 books. Most were theological except for those in two cabinets, one with books regarding antiquities and the other with books by Greek and Latin authors. Uffenbach comments on several books. One of these had a paper attached to it with handwriting by Petrus Scriverius. In the afternoon they visit the Oudemannenhuis. Uffenbach starts describing its building."
